Impact of substrate thickness on the rectangular patch antenna for 5G communication system by CST Studio

Abstract

An antenna is of extensive significance for a conversation device because the layout of an air interface is specifically reliant at the antenna layout. With the significant wireless evolution from 1G to 5G, technologies and network capacities are also evolving to full-fill the promptly growing customer demands. These continually increasing demands have gone concurrently with extensive technological accomplishments of the antenna design community. This paper discusses fifth-generation (5G) smart antennas, presents design of an efficient micro-strip antenna for 5G communication systems and the antenna is designed on low-loss Teflon based RT/duroid 5880 substrate with (ε_r) of (2.2) and a (tanδ = 0.0009) to wrap things up, and presented a comparative study of effect of height in the performance parameters of rectangular shaped micro-strip patch antenna, the antennas were simulated for purpose of the application of wireless LAN for (f_r = 28 GHz ) using CST Microwave Studio software, the performance of the designed antenna was analysed in terms of bandwidth, gain, return loss, voltage standing wave ratio, and radiation pattern (3D), the conclusion showed that the submitted designs have a bandwidth of (10 dB) greater than (2 GHz ), with an achieved total gain of more than (10 dB), the performance of the proposed antenna satisfies the requirements of 5G communications systems in terms of high gain, high radiation efficiency and adequate bandwidth.
